Abstract
Purpose:Our purpose was to investigate the influence of previous tuberculous epididymitis in patients with obstructive azoospermia on the outcome of sperm retrieval and intracytoplasmic sperm injection (ICSI).
Methods:Eighty-eight cycles of ICSI were performed in 44 patients with obstructive azoospermia; 16 cycles (7 patients) with tuberculous obstructive azoospermia and 72 cycles (37 patients) with nontuberculous obstructive azoospermia.
Results:The rates of fertilization and embryo cleavage were comparable, and there was no significant difference in the clinical pregnancy rate per fresh transfer between the two groups. The rates of embryo implantation and clinical miscarriage were also comparable.
Conclusions:Embryo quality and pregnancy outcome in sperm retrieval and ICSI were comparable in both the tuberculous and the nontuberculous obstructive azoospermia patients. Although there was a preponderance of testicular sperm used in the tuberculous obstructive azoospermia group, our results suggest that previous tuberculous epididymitis in patients with obstructive azoospermia does not affect the outcome of sperm retrieval and ICSI.
Keywords: obstructive azoospermia, tuberculous epididymitis, sperm retrieval, intracytoplasmic sperm injection, in vitro fertilization–embryo transfer
